02 3.4 4runner supercharged Maintenance question

aaronkim92 · 05-15-2012, 12:28 PM

Hey guys what's up.
So I was wondering. For spark plugs. Can anyone recommend any? Right now I have Ngk iridium .32 gapped. On all 6.
But others have been saying .4. So I'm like really worried.
Also, any ideas on how to get to the other 3 spark plugs. That's being pretty much blocked by the supercharger.

Also. Anyone know of a guide to remove a supercharger to get some engine work done?
Thank you

You can take off the bracket on the side of the motor, but in all honestly you can swap them with the S/C on no problem.

NGK IK22 or IK24 are the correct plugs, you can run stock gap as you don't want to ruin the iridium tip...

Ohhh okay it just seemed a bit close. I'll check again.
Ah! So does it matter if I use single prong ones instead of dual? Cause theres a sticker on the engine stating to use dual...

You can use either or.

You can also run V-power plugs (copper) but you will have to change them much more frequently (yearly) but they work well in boosted motors and are cheap.

Ohh sweet! I'll check those out. So iridium isn't always better than copper huh?

Do you recommend any gap settings? Or leave it stock? Say.. For the v power ones. (recommended to change out every year?)

BKR7E's are prefferred i believe.

Stock is BKR5E, BKR6E is one step colder than stock, BKR7E is 2 steps.

I ran coppers in my 3sgte and my bud runs them in his WRX, they are great as long as you change them every 10-15,000 miles. Some will say they work better than platinum's / iridiums as well... (just do not last nearly as long).

Take care of you're SC and just run the DENSO Iridium ik20, IK22 or IK24. Stock spark plug is an IK16, with 16 being the heat range. In looking at optional plugs, DENSO offers IK20, IK22, IK24, IK27 and a couple of others. The difference is only heat range, and the higher the number, the colder the plug. DENSO recommends for every 75 - 100 horsepower increase from stock, to drop down one heat range.
I have a set I would sell you for cheap (used <100 miles) or you can get them new off ebay.
